this is by no means a definitive answer, it's only 1 more of the "I can't make it happen" posts, but I'll say it anyway.
I'm a synthweaver. I really wanted to have crit-crafted rakata pieces. I have them now.
in process of making them, I have RE'd about 40 bracers/belts. I did not learn a recipe.
this is substantially more then my other (T1) failing streaks.
some time ago, there was talk of crit-crafting rakata trinkets; did we get a confirmation?
also, I'd suggest posting SSs of crit crafted saber/pistol and other important SSs in the OP.
